Problem-solving in criminal law - John Child

John’s research interests centre on criminal law theory, and particularly the internal structuring of offences and defences within the general part, where he has published widely. 

Across a range of criminal law topics, John's research aims to bridge the divide between conceptual debate and doctrinal application; and to demonstrate how a greater theoretical understanding of the law can be translated into an effective counter to the global expansion of criminal proscriptions (ie, inappropriate or over-criminalisation). This includes work challenging whether certain wrongs are deserving of criminalisation (eg, his work on prior-fault; complicity; inchoate offences; etc), as well as defending minimum doctrinal requirements within the law from philosophical critique (eg, his work on the voluntary act requirement). John is regularly engaged in collaborative and interdisciplinary projects that allow him to gain different insights into a legal problem, as well as to produce more robust recommendations for legal reform.
